Abstract

The utility model discloses a connecting terminal detonation pressure treatment unit, which is characterized in that the connecting terminal detonation pressure treatment unit is in a hollow cylinder shape and provided with a composite copper tube and a paper-shell case from inside to outside. A secondary explosive layer and a primary detonation explosive layer are arranged inside the paper-shell case from outside to inside, and a fuze is arranged on the primary detonation explosive layer. The connecting terminal detonation pressure treatment unit is reasonable in structural design and convenient in use, when the treatment unit is used, a sheath of a wire connecting end is stripped and sleeved with a connecting terminal prior to being detonated, wire heads at the connecting terminal are not scattered and surface of the connecting terminal is round and smooth when the composite copper tube is pressed by blast force, and thereby the wire connecting terminal is in fine contact with equipment, electrical reliability of the connecting terminal is improved greatly, construction is quite convenient, and the technical problem that the connecting terminal in the prior art is not ideal in treatment and easy to cause accidents is solved.

Description

Binding post is handled the detonation pressure device

Technical field the utility model belongs to binding post preparation implement technical field, relates to a kind of binding post and handles the detonation pressure device.

The mode of connection of the direct access type electric energy meter of background technology prior art is after the binding post exoperidium of lead is removed, and directly fills in the table mouth to compress with bolt.The reliability of this mode of connection is very low, because lead is to be made of stranded copper wire or aluminium wire, when using screw fastening, the lead unbalance stress if dynamics is excessive, can break the part lead, and the lead that has also contacts with electric energy meter table mouth.Cause and in fact have only several strands of wires at the conducting electric current; If firmly too small, problem is just bigger, has increased contact resistance greatly, particularly is applied on the aluminium matter lead, and aluminium material is too soft, and easily oxidation, and problem is particularly outstanding.According to rough Statistics, cause in the reason that direct access type electric energy meter burns out because the loose contact of table mouth cause account for the last ninety percent, the economic loss that causes is very huge, sometimes also can be because of causing the short circuit initiation fire behind the burning table, so loss is difficult to calculate especially.At present, handling the best mode of connection of connector lug is with hot method tining, both removes the external insulation skin at the binding post position, wrap up with tin liquor again, but this processing mode scene is difficult to accomplish, particularly small-sized job site is because the instrument that needs, material are too complicated.

The summary of the invention the purpose of this utility model is to solve prior art to exist binding post to handle undesirable accidents caused technical problem easily, provides a kind of binding post to handle the detonation pressure device, to overcome the deficiencies in the prior art.

To achieve these goals, the utility model binding post is handled the detonation pressure device, is open column shape, is provided with compound copper pipe and paper valve jacket box from inside to outside successively, be provided with secondary explosive layer and elementary ignition charge layer in the described paper valve jacket box from inside to outside successively, described elementary ignition charge layer is provided with fuse.

The utility model binding post is handled the detonation pressure device and is used to handle the aluminium matter lead wire terminal period of the day from 11 p.m. to 1 a.m, and described compound copper pipe is composited for three layers by aluminium, copper, tin from inside to outside successively.

When the utility model binding post processing detonation pressure device was used to handle the copper wires binding post, described compound copper pipe was composited for three layers by tin, copper, tin from inside to outside successively.

The utility model reasonable in design, easy to use, during use, earlier the lead wiring terminal exoperidium is disposed, ignite after overlapping upper connecting terminal then, can realize that under the effect of force of explosion extruding compound copper pipe binding post the end of a thread does not loose, appearance is mellow and full, smooth, make lead wiring terminal contact the purpose of the electric reliability that improves binding post well, greatly with equipment, and it is very convenient to construct, and has solved prior art and has existed binding post to handle undesirable accidents caused technical problem easily.

Description of drawings Fig. 1 is the utility model user mode sectional structure schematic diagram;

Fig. 2 is the right TV structure schematic diagram of Fig. 1.

Among the figure 1, lead exoperidium 2, lead 3, paper valve jacket box 4, secondary explosive layer 5, elementary ignition charge layer 6, compound copper pipe 7, fuse

Embodiment sees figures.1.and.2, the utility model is open column shape, be provided with compound copper pipe 6 and paper valve jacket box 3 from inside to outside successively, be provided with secondary explosive layer 4 and elementary ignition charge layer 5 in the paper valve jacket box 3 from inside to outside successively, elementary ignition charge layer 5 is provided with fuse 7; The utility model binding post is handled the detonation pressure device and is used to handle the aluminium matter lead wire terminal period of the day from 11 p.m. to 1 a.m, and compound copper pipe 6 is composited for three layers by aluminium, copper, tin from inside to outside successively; When the utility model binding post processing detonation pressure device was used to handle the copper wires binding post, compound copper pipe 6 was composited for three layers by tin, copper, tin from inside to outside successively.

The utility model is mainly used in direct access type electric energy meter, divides needs such as electronic box, earth leakage protective device directly to handle with the lead wiring terminal of bolt crimping.During use, earlier lead 2 terminals exoperidiums 1 are disposed, ignited after overlapping upper connecting terminal then.
